VANET SIMULATION NS3 PROJECT

In Vanet Simulation NS3 projects , the nodes are communicated using the IEEE 802.11p standard for wireless communication. Vehicles connected to each others through an ad hoc formation form a wireless network called as Vehicular Ad Hoc Network. VANETs are a subgroup of the MANET

 

Characteristics  of  VANET:

  • Unbounded network size
  • Crucial effect of security and privacy
  • Have high mobility of nodes
  • Real-time, time-sensitive data exchange
  • Rapidly changing network topology
  • Potential support from infrastructure etc.

 

Architecture of VANET:

VANET SIMULATION NS3 PROJECT

Challenges Faced in VANET SIMULATION PROJECT:

  • Network scalability
  • Mobility
  • Privacy Vs liability
  • Volatility

Privacy Vs authentication
